Amazon led all online retailers when it came to selling books, which is also not surprising. Borders leaving the industry, in part, has to do with the gain of the online marketplace over brick-and-mortar shops.

However, an interesting aspect was revealed when it came to Barnes & Noble, the second leading retailer of books. According to the report, B&N relied more heavily on print in 2012 than it did in 2011—going against the national trend. E-book spending declined from six percent to four percent from 2011 to 2012.
